Developmental Venous Anomalies

Background Developmental venous anomalies are considered benign lesions; however, they can become symptomatic. A capillary stain, which is an atypical angiographical feature of developmental venous anomalies, is reported to be relevant to symptomatic developmental venous anomalies. Case description A 20-year-old man with no pertinent medical history had an epileptic seizure. Magnetic resonance imaging showed severe focal oedema and gadolinium contrast enhancement in the right precentral gyrus and inferior frontal gyrus adjacent to the Sylvian fissure, indicating venous congestion; these presentations had not been observed on magnetic resonance imaging 8 months before. Digital subtraction angiography revealed a developmental venous anomaly with capillary stain. After conservative treatment, the brain oedema resolved spontaneously and contrast enhancement of the lesion reduced significantly. Conclusion We report a rare case of a symptomatic developmental venous anomaly with unique radiological characteristics and its natural and clinical evolution. Despite the presence of a capillary stain, our patient exhibited temporary exacerbations and spontaneous regression, suggesting that the capillary stain was associated with a reversible condition. This is the first report to detail the spatiotemporal changes of a developmental venous anomaly with capillary stain through imaging, suggesting that regular follow-up imaging is warranted in the management of patients with developmental venous anomalies.

Abstract Objective: We describe the intraoperative findings and results of an indocyanine green (ICG) video angiographic study in a patient with a developmental venous anomaly of the petrous veins. Clinical Presentation: A 56-year-old man sought treatment after experiencing lacerating facial pain on the right side for almost 2 years. His neurological examination results were normal. A magnetic resonance imaging scan revealed the presence of a venous angioma in close relationship with the trigeminal nerve and the intrapontine tract of its fibers. The patient underwent a retrosigmoid craniotomy to explore the cerebellopontine angle. Near-infrared ICG video angiography was used to study the venous pattern of circulation. The venous angioma did not appear to be the source of any compression and was left untouched. At the entry zone of the nerve root, the trigeminal nerve was found to be compressed by a loop of the superior cerebellar artery, which was moved and repositioned away from the nerve. Results: Near-infrared ICG video angiography disclosed an unexpected difference in filling time between developmental venous anomaly drainage veins and normal veins. The patient's pain resolved after microvascular decompression. Conclusion: Near-infrared ICG video angiography was particularly accurate and useful in the study of the venous dynamic of circulation. Further studies are required to confirm the supposed capability of ICG video angiography to differentiate developmental venous anomaly drainage veins and normal veins. Although magnetic resonance imaging supported the involvement of the venous angioma in the etiopathogenesis of this patient's trigeminal pain, surgical exploration disclosed a different cause.

Introduction: Incidence of diffuse axonal injury has been estimated at 40-50% of hospitalizations. Recently, much interest has been directed towards the potential of newer imaging sequences of magnetic resonance imaging to investigate diffuse axonal injury (DAI) and to prognosticate the outcome. In this study, we correlated the magnetic resonance imaging grades of diffuse axonal injury with clinical outcome in terms of Glasgow Outcome Scale (GOS). Methods and Materials: A hospital based observational study was carried out at Upendra Devkota Memorial National Institute of Neurological and Allied Sciences, Kathmandu in 69 patients of diffuse axonal injury between November 2017 to November 2018. Data was collected on patient and trauma characteristics, as well as neurological assessment and MRI findings. Outcome was assessed as favourable and unfavourable GOS for various MRI grades of diffuse axonal injury. Results: There were 21.74%, 42.03% and 36.23% of cases with grade I, II and III diffuse axonal injury respectively. There were 0 (0%), 2 (11.8%) and 15 (88.2%) cases of MRI grade I, II and III diffuse axonal injury in favourable GOS group and 15 (28.8%), 27 (51.9%) and 10 (19.2%) cases of MRI grade I, II and III diffuse axonal injury in unfavourable GOS group (p=0.00). Conclusion: This study showed that there was a significantly higher chance of unfavourable outcome with increasing MRI grades of diffuse axonal injury.

Longitudinal Observational Study

Introduction: Breast cancer is the most common malignancy in females worldwide. Mammography is a useful tool to diagnose breast cancer. Magnetic Resonance Imaging (MRI) has similar sensitivity like mammography to diagnose breast cancer, however MRI is more sensitive in diagnosing breast cancer in young females and patients with family history of breast cancer. Aim: To compare the sensitivity and specificity of MRI and mammography in the diagnosis of breast cancer. Materials and Methods: This was a longitudinal observational study done in the General Surgery Department of the study institute, from April 2018 to January 2020. Total 228 patients participated in the study. All patients, suspected to have breast cancer clinically, underwent mammography and MRI. The diagnosis was later confirmed by histopathological examination. The sensitivity and specificity of both MRI and mammography were determined by comparing with the results of histopathological examination using student’s t-test. Results: All 228 patients were females. In the study, it was found out that the sensitivity of mammography and MRI was 95% and 95.83%, respectively, in detecting breast cancer. The specificity of mammography and MRI was 89.28% and 83.33%, respectively. However, the differences were statistically non significant. Conclusion: From the study, it was found out that the sensitivity and specificity of MRI and mammography is similar in detecting breast cancer.
